In many real life situations, people work togetherusing their own computers. Such situations alwaysinvolve exchanging digital objects. It is then anatural idea to enlarge the view of individualvirtual spaces so that people may exchangeobjects in such workspace taking advantage of thecollaborators' physical proximity. In this work wepropose a means to allow people's collaborationthrough the interaction with objects in a commonvirtual workspace. We developed such approachas an application based on tablet pcs usingtheir several embodied resources. The concepts ofdynamic multiple displays and real world positiontracking were used, and a multiplayer gamewas implemented to demonstrate how users canexchange information through intercommunicatingtablets. Conclusions are drawn regarding theimpact of the new paradigm of extended multi-userworkspaces.
